Research in the field of Wireless Body Area Networks has been increasing remarkably due to the advancement of technology in the field of wireless communication and micro-electronics. These miniaturized sensors are being widely used in various fields of health monitoring due to their capability of providing real-time data to the patients. One of the main challenges associated with 3-D WBANs is to do with the life time of a network. The stringent requirements of the sensors used in WBANs such as battery operated devices opens up a challenge to hoard as much energy as possible. A lot of the energy is lost while transmitting the data to the base station. Therefore, we have attempted to reduce the energy dissipation of sensors by grouping them into clusters. We have introduced a clustering algorithm based on the computational geometry concept of Voronoi Tessellation. We adopt the two phase structure of Low Energy Adaptive Cluster Hierarchy (LEACH) protocol and design an enhanced version of LEACH by incorporating Voronoi based clustering. This algorithm is defined by weighing the significance of prioritized nodes and 3-D positioning of the sensors on the body as well. The simulation results demonstrate that our algorithm does indeed increase the network lifetime as compared to its conventional LEACH protocol approach.
